Quick Question...cake Batter In Pans/wait To Bake

Hi cc'rs I have a quick question....I just made a large batch of wasc chocolate cake. I poured it into two 9". pans, one, 7", and one 5"

Right as I was putting them into the oven, I got a call and need to leave for about an hour (pick up someone) Can I leave the batter (In the floured pans) out on the counter top in the pans for that long or will the mixture seperate and effect the outcome of the cake? Thanks so much!!! I don't want to waste all of this? Do I need to remix it when I get back?

oh great thanks!!!!!! So glad to hear. Haha i had it in my head that the reason they told you to flour the pans before you make the batter was so it would not separate...This was a complete guess though. Thank you so much!!!Jamie
